A new paradigm for geo-data acquisition

mapKITE is a new type of mapping concept in a well defined niche market (geoinformation in general, mapping more specifically, photogrammetry and remote sensing even more specifically) with companies (end-users of the technology) and companies/institutions (end-users of the geoinformation generated by the technology) prepared to operate and use the technology and results respectively.

mapKITE embodies many innovative ideas under the umbrella of two new paradigms: (1) the new tandem terrestrial-aerial geodata acquisition and (2) the use of the terrestrial vehicle to provide continuous ground control point information together with a new type of photogrammetric pointing-and-scaling measurements.

 

The new challenge of geoinformation

Geoinformation is a fundamental infrastructure of modern society as many other infrastructures and services depend on it (just to name a few, Location Based Services (LBS), smart cities, security and law enforcement, disaster management, land and catastral management, energy management or climate change monitoring). Yet, geoinformation –the modern 3D maps and beyond– is expensive to create and expensive to update. European, national and local governmental agencies in charge of geoinformation have to cope with a growing professional and popular demand for high-resolution, up-to-date geoinformation facing decreasing budgets. mapKITE eliminates the need for separate surveys –terrestrial separated from aerial– and uses low cost gears –small unmanned aircraft as opposed to manned aircraft–, presenting thus a much less expensive option delivering comparable or even better results. Its environmental impact (acoustic and pollutive) is also minor than traditional one as mapKITE is based on small UAs with electrical rotors as compared to bigger aircraft engines.

 

The contribution of European GNSS

The mapKITE concept fully exploits the GNSS positioning, navigation and timing (PNT) technology. We propose brand new ways of acquiring geodata and processing it to derive geoinformation that would make no sense without GNSS. In addition, we also highlight the critical role of GNSS timing, due to the need to synchronize the terrestrial vehicle trajectory solution to the central time of exposure of the remote sensing instruments of the unmanned aircraft. Thanks to the multipath-resilient and precise ranging properties of the Galileo E5 AltBOC(15,10) signal, we can guarantee a smooth navigation of the terrestrial vehicle and unmanned aircraft. EGNOS is an advantage in UA navigation as it delivers accuate and safe navigation without additional infrastructures -yet, but for those areas where WAAS or EGNOS are not available, the use of E5 AltBOC(15,10) signals still enables an accurate and safe navigation solution of the UA.
